Good day doc..ive been taking diane 35 for 9 mos now. Last month i was taking anitbiotic and mefenenamic while taking diane 35 as a compulsory for teeth extraction. Now for this month i was also taking celebrex while on the pill for 7 days then continued taking the pill.after 5 days i had unprotected sex.but prior to that i still did take the pill alloted for the day. Is there a possibilty i get pregnant?
